I also have this problem.

   uname -a
   Linux s8 5.10.16-0-lts #1-Alpine SMP Wed, 17 Feb 2021 08:17:06 UTC x86_64 Linux

In addition to the approach that max.m.mopp took, I also tried exporting the non-ZFS way, that is:

   zfs set sharenfs=off dataset

Then, create an export in /etc/exports.  And,

   exportfs -ra

This also does not work.  However, unlike the ZFS way of creating shares there is a difference.

When I try to create nfs shares the ZFS way and then run

   showmount -e server_address

on a client, I get a null response.  If I try exporting the non-ZFS way and run the above command on the client, the desired shares are shown.

However, when the following command is run on the client,

   sudo mount -t nfs -vvvv server_address:/home/myhome/myshare

the command hangs.  There is no response, even after tens of minutes.  (Note, the share is already configured in fstab.)

Seems like some plumbing between nfs and ZFS got lost along the way.

Any help would be extremely well received.

Thanks.
